Abstract

The semi-dry sand producing process and intelligent control technology consists of two parts including one semi-dry sand producing technological system and one automatic control system, and the automatic control includes through parts including the automatic control on the fineness modulus of artificial sand, the automatic control on stone powder content and the automatic control on the water content of the sand product. The present invention can raise engineering quality, lower engineering construction cost, raise the quality of sand product and the quality of concrete and eliminate environmental pollution.

Description

technical field [0001] The invention relates to a mechanical processing technology of artificial sand and gravel, in particular to an intelligent control technology of a semi-dry artificial sand production process. Background technique [0002] There are three types of sand making processes in the prior art: dry sand making, wet sand making, and semi-dry sand making. The dust pollution of dry sand making is serious, and only closed production can avoid the problem of dust pollution. The indicators of the finished sand produced by it are extremely unstable, because the production process cannot be well controlled, and excessive phenomena often occur; in addition, wet The French sand making process requires that the moisture content of the finished sand should be below 6%, which is not easy to control, and requires a large warehouse capacity for dehydration and drying of the artificial sand. The waste water discharge during the production process is large, and the loss of ston...
